    EVENING...
    A VERY WEAK FRONT MOVING ONTO THE COAST MONDAY MORNING AND INLAND
    LATE MONDAY MORNING AND AFTERNOON AND MONDAY EVENING WILL
    ENCOUNTER A COLD DRY AIR MASS IN PLACE OVER MUCH OF NORTHWEST
    OREGON AND SOUTHWEST WASHINGTON. SOME OF THE MOISTURE WITH THE
    SYSTEM WILL TEND TO EVAPORATE BEFORE REACHING THE GROUND...BUT
    THERE IS INCREASING CONFIDENCE THAT SOME LIGHT SNOW...SLEET...OR
    FREEZING RAIN WILL FALL...ESPECIALLY IN THE COLDER SHELTERED
    VALLEYS OF THE COAST RANGE AND THE CASCADE FOOTHILLS...IN THE
    INLAND VALLEYS INCLUDING THE WILLAMETTE VALLEY...THE COLUMBIA
    RIVER GORGE...AND THE UPPER HOOD RIVER VALLEY.
    THE MOISTURE WILL REACH THE COAST AND COAST RANGE FIRST MONDAY
    MORNING...BUT ANY WINTER PRECIPITATION AT THE COAST WILL BE
    BRIEF. THE WINTER PRECIPITATION IS EXPECTED TO REACH THE COASTAL
    VALLEYS MONDAY MORNING...AND POSSIBLY EVEN INTO THE SOUTH AND
    CENTRAL WILLAMETTE VALLEY BEFORE NOON AND BEFORE TEMPERATURES HAVE
    A CHANCE TO RISE ABOVE FREEZING. THE MOISTURE WILL SPREAD ACROSS
    THE REMAINDER OF NORTHWEST OREGON AND SOUTHWEST WASHINGTON MONDAY
    AFTERNOON...LIKELY NOT REACHING THE HOOD RIVER AREA UNTIL LATE
    MONDAY OR MONDAY EVENING WHERE A LITTLE LIGHT SNOW IS THE MOST
    LIKELY OUTCOME.
    ONCE TEMPERATURES INLAND SLOWLY RISE TO ABOVE FREEZING MONDAY
    AFTERNOON...THE THREAT OF FREEZING RAIN WILL DIMINISH AND THE
    MAIN THREAT WILL BE A RAIN OR SNOW MIX AS HIGHS MONDAY MAY STAY
    IN THE 30S.
    AMOUNTS INLAND ARE EXPECTED TO RANGE FROM A TRACE TO A FEW
    HUNDREDTHS OF A INCH AT MOST...AND THESE LIMITED AMOUNTS WILL
    LIKELY LIMIT THE ULTIMATE IMPACTS.
    NEVERTHELESS...THOSE TRAVELING IN NORTHWEST OREGON AND SOUTHWEST
    WASHINGTON MONDAY SHOULD USE EXTRA CAUTION AND BE PREPARED FOR THE
    POSSIBILITY OF SOME WINTRY CONDITIONS. CHECK THE NATIONAL WEATHER
    SERVICE AND THE OREGON AND WASHINGTON DEPARTMENTS OF
